or did I miss them? Hopefully 4 x the Merrils, if they shrunk the processors further while making for a new battery.

They did mention the battery model- is that the same of the Merrills? Need to check.

Someone in the rumor thread posted a picture of the newer batteries - I'm not sure if they are quite as big as the SD-14/SD-1 batteries, but they are much larger than the old ones. It's the reason for the large grip to one side.

Since there are about the same number of photosites, but newer electronics in the camera I guess 3x-4x is a decent estimate of the battery performance (that would be about 300-400 shots).
